BALL-AND-SOCKET PIPE-JOINT.

Specification of Letters Patent.

PatentediApr. 2, 1912.

Application filed July 7, 1911. Seria No. 637,348.

To all 'whom it may concern:

Be itknown that I, CLEMENS A. Kmn, a citizen of the United States, residing at Louisville, in the county of Jefferson and 1 State of Kentucky, have invented certain ts in Ball-andnew and useful Improvem the following a. joint of this kind which consists of only two pieces, and which is formed by casting the socket member around the finished ball member oi the joint.

In order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specification, in which drawing a central vertical section of the complete joint is shown. I

Referring specifically to the drawing, the

I joint consists of a ballmember 5, and a socket member 6. The ball member is first cast, and then finished true on the outside, and a thread 7 is cut in the bore of its neck, after which the socket member is cast around the ball member. The ball member is hollow, and' 'the bore of its neck opens thereinto. The socket member also has a 'neck provided with a threaded bore 11 openufactured.

The preferred embodiment of the invention has been shown, but it .will be understood that various'minor changes may be made without a departure from the spirit and scope of the invention.

The socket member. extends around the majdr port-ion of thefb all member and past the center thereof, and its inner end is in sliding contact with the-ball member at a point beyond the center thereof, in View of which endwise separation of the two members is prevented. This arrangement also renders unnecessary a packing, stufiing box, retaining ring or other devices usually employed for preventing endwise separation of 'the joint members. The structure is therefore greatly simplified, the complete joint consisting of only two members.

I claim:

A two-part ball-and-socket pipe-joint comprising a hollow ball-member having a hollow neck opening thereinto, and a socketmember extending around a major portion of the ball-member andin sliding contact with a narrow zone thereof beyoiiid the center of said ball-member to form a metal-tometal contact only, and to prevent endwise separation of the members, said socket-member having a neck provided with a bore which opens into the inside of said member.

In testimony whereof I aflix my signature in presence oftwo witnesses.
